STARTING JULY 25, 2020
Calling a 909 number? You'll need ten digits from now on.
Dial (909) + the seven-digit number.
Plus, an additional 840 area code will start serving the current 909 area beginning February 23, 2021
Who will be affected?
All customers who have a 909 or 840 area code telephone number will be affected. The 909 area code serves the southwestern portion of San Bernardino County, the eastern portion of Los Angeles County, as well as small portions of Orange and Riverside Counties. This includes the cities of Big Bear Lake, Calimesa, Chino, Chino Hills, Claremont, Colton, Diamond Bar, Eastvale, Fontana, Grand Terrace, Highland, Industry, La Verne, Loma Linda, Montclair, Ontario, Pomona, Rancho Cucamonga, Redlands, Rialto, San Bernardino, San Dimas, Upland, Walnut, and Yucaipa. The new 840 area code will serve the same geographic area currently served by the existing 909 area code.
What is the new dialing procedure?
To complete local calls, the new dialing procedure requires anyone with a 909 or 840 area code to dial area code + telephone number or 1 + area code + telephone number. This means that all calls that are currently dialed with seven digits will need to be dialed using ten digits.
When will the change begin?
Beginning July 25, 2020, you should begin using the new dialing procedure whenever you place a call from the 909 area code. If you forget and dial just seven digits, your call will still be completed.
Beginning January 23, 2021, you must use the new dialing procedure, as described above. On and after this date, if you do not use the new dialing procedure, your calls will not be completed, and a recording will instruct you to hang up and dial again, including the area code.
Beginning February 23, 2021, new telephone lines or services in the 909 area may be given numbers from the new 840 area code. Anyone that receives an 840 area code telephone number must use the new dialing procedure described above.
What will I need to do?
In addition to changing your dialing procedure, all services, automatic dialing equipment, or other types of equipment that are programmed to dial seven digits —will need to be reprogrammed to use the new dialing procedure. Some examples are life safety systems and medical monitoring devices, PBXs, fax machines, Internet dial-up numbers, alarm and security systems or gates, speed dialers, call forwarding settings, voicemail services, etc. You may also want to check your personal and business stationery, checks, advertising materials, websites, contact information, and personal or pet ID tags to ensure the area code is included in the telephone number
What will remain the same?
- Your telephone number, including current area code, will not change.
- The price of a call, coverage area, or other rates and services will not change due to the overlay.
- What is a local call now will remain a local call regardless of the number of digits dialed.
- You can still dial just three digits to reach 911.
- If 211, 311, 411, 511, 611, 711 or 811 are currently available in your community, you will still dial these codes with just three digits.
